Its not an aside, its centrally related. The technical version of the app enables the problematic activity to scale and thus the moral and ethical implications are centrally related to the technical implmenetation.

You mean just like a centrally fabricated ID card that's used for entering an airport, making certain purchases, verifying ID for a CC purchase, entering the country, etc?

Would you be happier by checking equivalent paper printouts, check done by hand?

What public service does the government forbid me to access without my papers (except the ones where the document is needed to charge the state for the service - eg. medical stuff)?

Just a year ago, saying that the governments will require you to produce a "vaccination passport" to enter a restaurant was laughed at as a crazy conspiracy theory, and currently, the difference between a "crazy conspiracy theory" and "reality" is about 6-12 months.

"certain or public services" was the phrase the parent used. I just said the same rules apply as before. Maybe you are better off asking them for examples.

What public services does the government forbid you to access without a Covid vaccine? I am not aware of any.

If you are talking about private services, then there are many examples where papers are needed:

• buying alcohol (ID)

• entering a nightclub (ID)

• taking a plane (ID)

• opening a bank account (SSN/ITIN)

• renting a car (driver's license)

• buying a gun (proof of residence)
